Qs on changing from stock (T-Mobile) on IN2017 - OnePlus 8 Questions & Answers

Hi all, I am on Mint, and have issues getting calls in on the phone - T-Mobile sim unlocked OP8 - IN2017. The sim works perfect on my OP6T where I had flashed the Global Rom. So, if any could give some input on the following:
*Do you think flashing the Global/or a custom ROM could help with incoming call issue?
*Will flashing away from the Stock ROM lose any T-Mobile bands in the USA?
*What would I lose in flashing to the Global ROM (on 6T lost ability for Google Pay - assume still the same issue?)
*Would it be better to Flash to Global ROM, or to one of the Custom ROMs (like Lineage)?
*I assume if i mess anything I can go back to stock?
I am waiting for bootloader unlock code from OP. Thank you for any input.

Not sure about the bands but I get decent speeds on the global. As far as I know everything still works. I use google pay every day. The only thing you need to do to get it working again is relock the bootloader. The rom or stock thing is pretty much personal taste. I like oxygen os so I've stuck with stock.

Thank you for the reply. So you went from T-Mobile stock OOS on the IN2017, to Global OOS? Everything seems to work well, that is good. So no need to root for GPay, just re-lock bootloader, that is good to know. Are you on Android 11? Did you lose 5G?
Do you have a guide that you used, and liked, for the conversion to Global? Did you backup your persist.img prior?

LG G5 Software version H83020i_un

This is an unlocked T-Mobile G5, but why have a special ROM for unlocked phone? I wonder if I flash other ROMs, I could lose the unlock. Anyone have any problem rooting and install twrp?
Conclusion after a month long discussion:
G5 with H83020i_un ROM is NOT factory unlock. Upgrading or downgrading will result in SIM lock to T-Mobile, period.
Once locked, it can only be unlocked by T-Mobile customers via T-Mobile unlocked app. Some has to go thru T-Mobile customer service and request SIM unlock by adding IMEI to their database.
I bought 6 (New to New other) unlocked H830 and 2 has the hacked ROM H83020i_un and 4 were completely locked to T-Mobile. Yes, those stupid sellers on ebay just keep sending lock phones as unlocked phone! Good luck getting a unlocked one.
No, you cannot install TWRP or root this version.
I ended up returning mine.
You shouldn't lose the unlock by flashing another ROM.
A ROM isn't just about 'locked or unlocked'. The ROM is the operating system. While it will still be Android no matter what you do, different ROMs are modified differently to provide additional features, or more control over the settings or just a slightly different user interface.
This has NOTHING to do with the phone being unlocked for use on any GSM network.
For example some people want to be able to control the CPU processor speed on the phone more. Some ROM's give you that control built into the settings and use customer kernels that allow the CPU to run faster than it does running stock. Other people just like a more simple UI that you get on base Android ROM's (rather than some of the overlays LG puts on)

I can't confirm this personally, but @autoprime mentioned on IRC that everyone who tried flashing other KDZs over this specific firmware lost the SIM unlock.

I don't know when people will understand that it has nothing to do with sim unlock. I have T-Mobile unlocked sim lg g5 and flashed roms, custom and stock both several times and never had any problem with sim lock stuffs. Just install twrp, root, flash custom rom, there will never hurt anything in your phone.

It seems that this is not a regular unlock. When I open the T-Mobile app, it says the phone is still locked, but it works anyway.

Did you confirm that by trying the phone with a non T Mobile SIM on a different network? Or did you just let the T Mobile unlocker app tell you it's still locked?
The app isn't the most reliable thing in the world. It's known to say it's not unlocked when it is or that it can't be unlocked when it already is. Etc etc...
Unlocking it manually (through codes, ADB, root, etc....) messes with the unlocker app. But the unlock itself should still be valid.

Maybe it is something to the specific phones people are getting from the ebay seller. They are being sold as new yet are not factory sealed and missing the Tmo sim card. People are claiming Android pay doesn't work and the phone isn't rooted. A new out of the box phone shouldn't have that issue. So something isn't necessarily kosher.
Guys, I have the same version (H83020i_un) and it has April security update and T-Mobile has different version #s on their website. I have checked for update, but nothing came up. So I can't get T-Mobile updates?
The software version H83020i_un is apparently not an official ROM released by T Mobile or LG.
There is a lot of speculation on Slickdeals (a website for coupons and stuff where this eBay deal has been discussed quite a bit) that the unlock was done by flashing a modified ROM. If so that would explain why flashing a new ROM loses the unlock.
Additionally people are saying that Android Pay doesn't work on this phone with that software update, presumably because it's not official firmware. I've never used Android Pay so I have no idea if it works or not.
All in all if you have the H83020i_un software and bought the phone 'new' I think you got conned. It's not new and that seems to be unofficial software.
I spent a lot of time, with help from @autoprime, trying to figure out where the unlock is stored. I was able to dump the partitions from 20i_un using the method here. After I downgraded to 20A and flashed TWRP, I flashed back all the 20i_un partitions (besides recovery, cache, and userdata), and it still wasn't unlocked. So I'm baffled as to how the unlock works.

I see. It will be used as a second device, so it is fine. I flashed the phone with stock T-Mobile H83020a, then got few OTA updates. Now my phone has H83020i, but T-Mobile's page(below) shows an "f" version as the latest. So is the H83020i, the latest update or not? Also would be good if anyone with real T-Mobile unit could chime in.

T-Mobile 7 Pro converted to international; Couple root/bootloader questions.

Today I received a T-Mobile, SIM unlocked, OnePlus 7Pro GM1915.
I have already followed the steps to flash international firmware and that went fine. Only issue I had was my SIM was being detected but no service, an OTA update to 10.0.3 fixed that issue. I haven't had a phone with root access/unlocked bootloader since my 1st gen Moto X so excuse my ignorance if some of these question are common sense, but I've done some searching online and can't find any straight forward answers.
1. Now that I have installed the international firmware I don't need to get a bootloader unlock from T-Mobile, correct? I can just use the OEM unlock option and unlock via fastboot?
2. I know bootloader/root can sometimes cause certain applications to not function, but I've also read Magisk has a setting to correct this. I'm mainly just concerned with Google Pay, is there a method for it to still function with root?
3. Part of me would actually like to use the phone stock for a week or so to see if I even feel like I need root access. I am currently on OS 10.0.3, if I update to the newest OS (looks like 10.3.1 is the newest) will I still be able to root with Magisk? I would assume yes since you can do an OTA update and keep Magisk, but I just wanted to verify.
Again, sorry if some of this is common sense, but I've searched around and can't find straight forward answers fort any of this.
First, sim unlocked you're good to go. No need to bother T-Mobile. Bootloader unlock is through OnePlus. Guides aplenty here, search will turn up what you need. I'm personally running the box stock firmware unrooted and at the moment I'm very happy with it.fotr the first time in a long time I don't see much value in going through the process of rooting because the stock ROM pretty much has everything that I used to get with rooting and a custom ROM. I will probably do it anyway at some point, just because I feel wierd not having root.

Thanks for the feedback.
I think I'm going to update to the newest firmware. Worst case I decide I want to root I'll use MSM and downgrade, my phone will get wiped when I unlock my bootloader anyway.

Your current version does not matter. This will flash phone to point that it was when it came out of the box. then you can start over.
Do i lose unlock after convercion
How do you back up the T-Mo modems without going thru the T-Mo bootloader token unlock? I want to try going back to the T-Mo modems to see if they resolve the issues, and then back them up when to reflash when I go back to the EU load.
Thanks!

Yep. Any critical partition flashing has to be unlocked. There is no other way around it. I've bricked my 9,the one before this one,by flashing the wrong modem on it. Tried MSM and it locked it and I couldn't do anything else to it,meaning flashing anything through bootloader or fastbootd.

Well, I guess it ended up not mattering much in the end. At least for what I was trying to do.
I'm finding T-Mo's service to just be complete crap, and I've determined it's not the phone. I moved 8 lines over from AT&T. Half were BYOD (all unlocked AT&T Samsung devices, and my son's unlocked OP9), and the other half were Samsung and OP phones bought from T-Mo. Everyone's experiencing bad call quality and coverage issues. Both my family and in-laws live within a mile from known T-Mo towers where we live. I live in a major metro area, my in-laws in a rural area. My parents live in a medium sized city. It's gotten unbearable, and at times, my wife and I have had to resort to texting due to the call quality just being so bad. Cutting out, garbled, etc.
In-laws also have T-Mo's home internet and are having issues with that.
I don't get it despite everything good I've read about T-Mo. None of us had these issues with AT&T.
I'm going to try to work it out with T-Mo, but at least for the time being, I'll just go back to the European ROM. There's no difference in the call quality anyway, and at least there I have root again.
If i flash the T-mo firmware to a global model, will I be unable to unlock the bootloader simply with the adb command, or will I have to go through all the hoops as if I bought the phone directly from t-mobile?

I'm gonna use the T-Mobile sim card on a global version of the phone. So theoretically the phone would already have been sim unlocked out of the box. What I'm asking is, if i choose to use the T-Mobile msm on the unlocked global model, will it carrier lock me in? If not that means all i have to do is go to developer options and use the unlock command, right?

No that won't happen to you. You should still be SIM unlocked as flashing software doesn't deal with SIM Locking but it May Lock the Bootloader that I am not Sure of

Question T-Mo Temp Root/Modem Backup?

Hey all,
I've been on the Global then EU Roms more or less since day 1. I've been having a lot of call quality issues and it's looking like I'm going to have to revert back to the T-Mo ROMS at least temporarily.
I unlocked my bootloader after switching to the global rom. I really don't want to go thru the whole T-Mo unlock token thing after reverting. Could I get temporary root by booting from a patched Magisk image on my PC, then back up the modems with Partition Manager? Or could I extract the modems from the T-Mo images/OTAs and flash them?
I don't like the bloat in the T-Mo load and want to go back to EU afterward, but the phone's call quality, BT, and data speeds (cell and Wifi) are atrocious as it currently stands.
Any guidance or thoughts on the best way to proceed?
Thanks,
Super
Do you not still have the unlock.bin from the first time you unlocked? Just MSM, fully patch, then dump boot with edl and patch it
No. I didn't need it. I switched to global first then I was able to unlock as normal without it.

BL unlocking/custom ROM Question: What is permanently lost if I do that?

Hi,
Just grabbed an Xperia 5 II on a great deal and I'm loving this device. It's an A002SO. I have noticed in other threads that there is some loss with original functionality of the phone (maybe Dolby or some other features are broken even if phone is restored to stock). Is it true? And if so what features are broken.
I noticed that Xperia camera software are available for other roms too which is great but what about device fingerprint and BL unlock sensing protection for banking apps? (I am not interested in rooting the phone after flashing lineage/AOSP roms but more concerned about the broken safety net in-case I go custom ROM route)
Also, is there a risk of losing IMEI with all this process? Not talking about crossflashing here but would love an AIO guide about BL unlock > recovery > ROM and the Back to stock locked bootloader guides if there are any.
Thank you!

I have a different model, but I recently went from stock to Lineage OS, then back to stock. I haven't had any issues. Dolby works, my data/LTE works, and I can still use my banking app just fine. Fingerprint detection was a bit more finnicky with Lineage OS, though.
I should also note, I'm currently rooted with my bootloader unlocked, and still no issues.

I gave up in the end because my device is Japan Softbank with bootloader unlocking not allowed. Crossflashing instructions have alot of "you can", "I think" but no definite root-to-fruit guide so I may convert it to global model and BL unlock without losing imei / 4G. Thank you for taking time to write the clarification.

I don't actually know if that would work... I don't mean to give you another indefinite answer, but I tried that once on a Japanese Xperia 10 II. I know it's a different device, but it may still apply in your situation. I would still try it, though. Worse case scenario, you have to use Sony's repair tool to get back to stock.
(Also, if you're interested in a non Japanese model, I am currently selling my 5 II.)

I am from Pakistan so it's gonna cost me double the actual price to pay customs taxes and get it cleared for use in-country. Our country has a rule about only the devices which are approved after paying hefty taxes, are permitted on Pakistan's cellular operators.
This was discussed before, in short you seem to lose out certain manufacturer keys and your phone remembers you have unlocked its bootloader before. As for functionality, iirc they seem to come back after relocking.
